We performed an experimental study to investigate the effects of structural strategy for improving the debris brake performance. The stony debris flow was generated by releasing water discharge from a tank that contained gravel material. The efficiency of debris brake, debris accumulation pattern and its position parameters was used to evaluate the performance of the debris brake structure. The influences of debris brake slope, opening size and nonuniformity in deck opening size parameters that have not been studied before were investigated for different debris flow conditions. The results showed that the slope of debris brake was the most important factor on debris brake performance. The suitable slope was found to be a function of the debris flow velocity, and it can increase debris brake efficiency up to 10%. The analysis of the experimental data suggests the optimum opening size ratio (i.e., the ratio of opening size to median diameter of debris) smaller than or equal to one. Experimental data indicated that the nonuniformity in opening size of the debris brake cannot improve the debris brake efficiency.

碎屑制动性能结构策略的实验研究

我们进行了一项实验研究,以研究结构策略对提高碎片制动性能的影响。石质碎石流是通过从装有砾石材料的水箱中释放水而产生的。碎屑制动效率、碎屑堆积方式及其位置参数被用来评价碎屑制动结构的性能。针对不同的泥石流条件,研究了泥石闸坡度、开口尺寸和甲板开口尺寸参数不均匀性的影响,这些参数以前尚未研究过。结果表明,碎屑制动坡度是影响碎屑制动性能的最重要因素。发现合适的坡度是泥石流速度的函数,它可以将泥石流制动效率提高 10%。对实验数据的分析表明,最佳开口尺寸比(即开口尺寸与碎片中值直径的比值)小于或等于1。实验数据表明,碎屑制动器开度大小的不均匀不能提高碎屑制动效率。
